Sexuality

So homosexual marriage finally seems like it's getting approval from the American public, to which I say Kudos! I'm firmly attracted to the female form myself, but I'd never want to keep someone from marrying someone else.

I'm not sure you'd want to use the term "disease" though. There's no such thing as a good disease and, by definition, all diseases have adverse effects on the diseased. Homosexuality doesn't have an adverse effect - not a physical one, at least. It doesn't even really hinder reproduction. The need and desire to reproduce is still a part of many homosexuals (as many adopted children and surrogate mothers can attest to) and the ability to reproduce still exists. True, heterosexual desire is meant, from a natural standpoint, to increase reproduction but that doesn't mean that the desire to reproduce doesn't exist outside heterosexual desire.

Rather than a disease, I'd just call it a personality trait.

Yeah. Calling it a disease makes it sound like you pity the person for having it, and that they really shouldn't have it. In the current social climate regarding tolerance, it's not a good idea.

So, not "disease." Perhaps it could be called an "abnormality" or "dysfunction." I mean that psychologically or whatever--like they have a dysfunction; not that they are, themselves, dysfunctional. "Abnormality" seems okay to me because I would define heterosexuality as normal (ie. of the norm), thus being an outlier from normal would then be abnormal.

I wouldn't say it's "genetic" though--at least not entirely. Perhaps there is a genetic predisposition toward it, but I disagree both that it's entirely genetic and... for lack of a better word, "uncurable" (I really tried to think of a different word) as people (my cousin for example) are fully capable of first being hetero, then turning gay, and then being hetero again.

EDIT: Someone will want to respond to this by referring to Kinsey's sexuality continuum (ie. people can be partially gay/hetero), but I'm just referring to being gay according to two factors: 1) are you presently having same-sex physical encounters; and 2) do you desire to have same-sex physical encounters.

Again, the current theory is that this is an epigenetics thing, not a pure genetics thing. This explains why there's a spectrum of sexualities. Depending on the amount and types of hormones a fetus receives at birth, the certain genes will be turned off and on and the sexuality of the resulting baby will be different.
